Definitions

  • the invention relates to a juicer that is driven by an electromotor and that has a central projecting element that tapers in the upward direction for pressing a piece of fruit, the juicer being drivable by the electromotor at a first rpm given actuation of a first switching device.
  • European Patent EP 0 362 058 B1 describes a juicer that is driven by an electromotor. There, the motor, by a drive belt and pulleys, drives a shaft at the top end of which the juicer is disposed together with an upwardly tapering element that projects from the middle thereof.
  • the known juicer can be driven at rates of rotation between 2000 and 2500 rpm.
  • the activation of a known motorized juicer is realized either by the actuation of a switch by the user setting the electromotor in rotation, or by the exertion of pressure on the element by the user activating the juicer by a lever mechanism that is connected with it working in conjunction with toothed gearwheels.
  • a juicer including an electromotor having at least two driving speeds, a first switch connected to the electromotor, a second switch connected to the electromotor, a centrally disposed element projecting upward in a taper for pressing a piece of fruit, and the electromotor being operatively connected to the element and rotationally driving the element at a first speed upon actuation of the first switch and at a second speed greater than the first speed upon actuation of the second switch.
  • a juicer including an electromotor having at least two driving speeds, a first switch connected to the electromotor and switching the electromotor to a first driving speed, a second switch connected to the electromotor and switching the electromotor to a second driving speed greater than the first driving speed, a centrally disposed element projecting upward in a taper for pressing a piece of fruit, and the electromotor being operatively connected to the element and rotationally driving the element at the first driving speed upon actuation of the first switch and at the second driving speed upon actuation of the second switch.
  • a juicer including an electromotor having at least two driving speeds, a first means for switching the electromotor to a first rotational speed, a second means for switching the electromotor to a second rotational speed greater than the first rotational speed, a centrally disposed element projecting upward in a taper for pressing a piece of fruit, and the electromotor being operatively connected to the element and rotationally driving the element at the first rotational speed upon actuation of the first switching means and at the second rotational speed upon actuation of the second switching means.
  • a juicer according to the invention provides a second switching device with which the element can be driven at a second, higher speed.
  • the pressure that is automatically exerted on the element by the user when she wants to press a piece of citrus fruit simultaneously produces electrical contact and switches the motor on.
  • the additional switching device is, then, actuated, the rpm is increased again, for instance, to 4,000 rpm.
  • the juicer is characterized by actuating the second switching device by a button.
  • the button is particularly easy to access when it is disposed on a jacket wall or exterior housing wall of the juicer.
  • FIG. 1 is a cross-sectional view of a juicer according to the invention
  • FIG. 2 is a fragmentary, enlarged, cross-sectional view of a switch of the juicer of FIG. 1 ;
  • FIG. 3 is a block and schematic circuit diagram of the juicer of FIG. 1 ;
  • FIG. 4 is a perspective view from the side of a housing of the juicer of FIG. 1 .
  • juicer 1 having an electromotor 2 as drive motor. This drives onto a drive shaft 3 .
  • a toothed gearwheel 4 At the end of the drive shaft 3 is a toothed gearwheel 4 , which meshes with a toothed gearwheel 5 .
  • the toothed gearwheel 5 is fastened to a drive shaft 6 .
  • the drive shaft 6 bears an element 7 that is shaped like a rotation paraboloidal, cone, truncated cone, or hemisphere.
  • the element 7 includes ridges with depressions in between, which serve for pressing a piece of fruit.
  • the pressed juice runs into a collecting container 8 that surrounds the element 7 and rotates together with it by the drive shaft 8 .
  • This container includes slots from which the juice flows into a stationary bowl 9 .
  • the underside of the element 7 is connected to a collar 10 , which is fixed to the drive shaft 6 .
  • the collar 10 contacts a shaft sleeve 13 by way of a compression spring 11 and a sliding disk 12 .
  • the drive shaft 6 actuates a rocker switch 15 that is fastened at attachment point 14 ( FIG. 2 ) and that can be pivoted about its free end so that the switch presses against a caliper 16 .
  • the caliper 16 is received by a housing retainer 17 .
  • the electromotor 2 With the closing of a switch contact 18 ( FIG. 3 ) by the caliper 16 , the electromotor 2 is actuated and drives the element 7 together with the collecting container 8 by the drive shafts 3 , 6 , the gearwheels 4 , 5 , and the collar 10 , whereby juice is pressed from the fruit.
  • the electromotor 2 and the switch contact 18 are part of an electrical circuit that is supplied with a voltage V.
  • the circuit contains a microcontroller 20 that is clocked by a clock 19 and that, by way of a control line, controls a triac 22 by which the electromotor 2 is controlled.
  • a rectifier bridge circuit 23 is connected in series with the electromotor. Coils 24 , 25 serve for signal smoothing.
  • a switch 26 is contained in the circuit. Actuation of the switch 26 is by a button 27 ( FIG. 4 ) that is disposed on an exterior housing wall 28 and causes a higher current to be supplied to the electromotor 2 based on a corresponding actuation by the microcontroller 20 . Thus, the electromotor 2 rotates at a higher speed.
  • the circuit is wired either so that the switch 26 must be actuated in addition to the actuation of the switch 18 , or so that either the switch 18 or the switch 26 is actuated.
  • a switch 26 is provided for causing the juicer, namely the element 7 that receives the fruit, to rotate, at a given rpm.
  • the microcontroller 20 is actuated to supply a higher current to the electromotor 2 and to cause it to rotate at a speed higher than the given rpm.
  • fruit juice is pressed from pulp that has already separated from the fruit.
